To all whom et may concern.'

Be it known that I, CARL P. Mrciinnson, a citizen of the United Statesof America, residing at Mason, in the county of Ingham and State ofMichigan, have invented certain new and useful Improvements in PortableRefrigerating-Cases, of which the following is a specification,reference being had therein to the accompanying drawings.

rfhis invention relates to a portable refrigerating case and its objectis to provide a receptacle having the appearance of an ordinarytraveling bag provided with the usual handle by means of which it may bereadily carried. and having an internal arrangement whereby a receptacleis thoroughly cooled by a circulation of water from an ice chamber andall liability of leakage obviated.

The invention consists in the matters hereinafter set forth and moreparticularly pointed out in the claims reference being had to theaccompanying drawings in which,

Figure 1 is a longitudinal vertical section through a device embodying'the invention; Fig. 2 is a transverse vertical section of the same; andFig. 3 is a perspective view of the device with the ice receptacle andcarrying receptacle partially withdrawn.

A suitable casing 1 is preferably made in a form approximating that ofan ordinary traveling bag with the usual handle or hand grip 2 securedto the top of the receptacle which is formed with a rib 3 provided withdevices t representing the usual fastenings upon a traveling bag andalso with a device 5 representing a lock. These devices l and 5 performno function further than to give to the receptacle the appearance of atraveling bag. The top wall 6, side walls 7 and bottom wall 8 are allformed double with a space between the walls which space is filled witha suitable insulating material 9 such as corrugated liber board toprevent rapid radiation and keep the contents from heating. A third wall10 is spaced from the double wall to form a water space t1 extending allthe way around a bottom chamer 12 which is provided to receive a suit,ably shaped receptacle 13 for carrying fish or other material which itis desired to keep cool. The wall 10 also forms a second chamber 14 inthe upper part of the casing directly above the chamber 12 and an icereceptacle 15 is formed to tit closely within the chamber 14 it beingsupported along its lower edges upon a ledge 16 formed by inwardprojections of the wall 10. A door 17 is provided in the end of thechamber 14 through which door opening the ice receptacle may beinserted. This door is held in place by a suitable latch 18 of anydesired construction and upon the end of the ice receptacle adjacent tothe door is formed a downwardly extending tubular spout 19 which titswithin an enlargement of the water space 11, said enlargement beingformed by an inward depression of the wall 10 which forms a funnel 2O toreceive the tubular discharge spout 19 on the ice receptacle. As the icemelts the cold water drains through the spout 19 into the water space 11surrounding the chamber 12 and thus the receptacle 13 is kept cold bythe lilm of ice cold water surrounding the chamber. The capacity of thiswater space l1 is preferably made substantially the same as the capacityof the ice receptacle so that when the ice is all melted the w'aterspace will be filled with water and there will be no liability of anyleakage.

The ice receptacle is illed through an opening in its bottom which isclosed by a screw cap 21. The ends of the receptacle 13 are preferablyrounded at their lower corners as shown at 22 so that the receptacle maybe easily cleaned and will slide into the chamber 12 without binding,access to said chamber being gained through an end opening in the endw'all of the casing which opening is closed by a suitable door 23 heldin place by a latch 24 of any desired construction. The door 23 ispreferably located in one end wall of the casing and the door 17 in theopposite end wall. The ice receptacle 15 and the receptacle 13 aretherefore withdrawn through opposite ends of the casing and thisarrangement brings the discharge nipple 19 on the ice tank adjacent tothe door 17 so that it will slide into the funnel 2O and the receptaclewill engage and make a tight joint with the funnel.

Obviously, changes in the construction and arrangement of parts may bemade without departing from the spirit of my invention and I do not wishto limit myself to the particular form and arrangement shown.

Having thus fully described my invention what l claim ist- 1. In adevice of the character described7 the combination of a casing havingopenings in the ends thereof7 and formed with a Water space extendingalong the sides, end and bottom of the casing, a longitudinallyremovable receptacle in the lower part of the casing, an ice receptaclelongitudinally removable through one of the end openings in thereceptacle and fitting Within the upper part thereof, a discharge nippleon the bottom of the ice receptacle opening into the Water space, andclosures for the openings in the ends of the casing.

2. In a device of the character described, the combination of a casinghaving a double Wall forming a Water space extending along the sides,one end and bottom of the casing, said casing being also formed Withopenings in its opposite ends, a handle secured to the top of thecasing, an ice receptacle fitting within the top of the casing andremovable longitudinally through one of its end openings, a funnel onthe Wall of the casing adj acent to the opening through Which the icereceptacle is removable, anipple on the bottom of the ice receptacleadapted to project into the funnel and discharge into the Water space, areceptacle in the lower part o-f the casing removable longitudinallythrough an opening in the end Wall of the casing, and closures for theopenings in the ends of the casing.

In testimony whereof I affix my signature in presence of two Witnesses.
